In the PHP manual:
"Note: HTTP/1.1 requires an absolute URI as argument to Location: including the scheme, hostname and absolute path, but some clients accept relative URIs."
The  header statements in base.main.php use a relative URI, not an absolute URI.
When I change the relative URI to an absolute one, things now work on IIS 6.0.
I think that all  header("Location:  code lines should be changed to absolute URIs.

I'm using IIS 6.0.
I'll try this with Apache tomorrow.

I get a hard hang on my web browser when I click on the   Use Archive Database  link.
This is with both IE6 and Firefox and for both V1.2.5 & 1.2.6.
I've isolated the problem to these statements on lines 80 and 86 (V1.2.6) in base_main.php
    header("Location: ". $BASE_urlpath . "/base_main.php");
If these lines are commented out, then the   Use Archive Database  link now works for me.
Anyone have a clue as to why?
